Abstract

The present invention discloses a self-adaptive equal rigidity vibration isolator based on magnetic levitation damping three-dimensional decoupling, and mainly relates to the three-dimensional vibration isolation field of high-end electronic equipment. The self-adaptive equal rigidity vibration isolator comprises a vibration isolation housing, a three-dimensional levitation block, a connecting platform, a platform straight rod and magnetic levitation damping systems; in the X, Y and Z directions, two magnetic levitation damping systems, two magnetic levitation damping systems and one magnetic levitation damping system are respectively installed between the vibration isolation housing and the three-dimensional levitation block; and in the X, Y and Z directions, the magnetic levitation damping systems are mutually independent, that is three-dimensional rigidity is decoupled. The self-adaptive equal rigidity vibration isolator based on magnetic levitation damping three-dimensional decoupling is reasonable in structure, the three-dimensional rigidity is decoupled, and the rigidity can be adaptively controlled.

Description

Technical field [0001] The present invention mainly relates to the field of three-way vibration isolation of high-end electronic equipment, and particularly refers to an adaptive equal stiffness vibration isolator based on three-way decoupling of maglev damping. Background technique [0002] The vibration isolation of high-end electronic equipment usually requires the isolator to have equal stiffness performance in three directions, and the stiffness of the isolator is required to be automatically adjusted. The existing electronic equipment vibration isolators mainly include metal spring vibration isolators, steel wire rope vibration isolators, rubber vibration isolators, etc. These vibration isolators have some common defects: the stiffness of the three directions is quite different; the stiffness is not able to Spontaneous active regulation. [0003] In the prior art, the patent 201210449640.1 discloses a three-way equal stiffness metal vibration isolator, which successfully sol...
